TO ALL WHOM IT MAY GONCERN:

Be it known that I, A. B. SMITH, of Rochester, in the county of Beaver,and AState of Pennsylvania, have inventedan Improved Construction ofEndless Platforms' 'for Cham-Powers.; nndI do hereby' declare tiret thefollowing is a lull and exact description thereof, Ireference being` hadto the accompanying drawings, making part of this specification-- Figure1 beings. top vjew of ls. 'portion of the endless-platform driver, inthe construction of whih my invention consists.

`Figure.2, an edge view of the same. Figure, a. bottom view of a portionthereof. Figure `4, a. side view o' it part detached. Like lettersdesignatecorresponding parts'in all of the gures. The lags orcross-steps A A` of the endless revolving platform or track, are\secured at the'two ends respecte ively to two flexible bands B B,preferably of leather orIndia-rubber belting,iwl1iel1 take the place ofchains or conn'rioting-links, v

In order t'o give firmness and rigidity against sagging to thisplatform, I employ a. double series of eti`enerbraces or cleats, C C,onefor each lag, at each end, opposite tothe connecting-bandsrespectively. Each brace (as representedlis composed of metal, has ecentral eye, b, to receive a. rivet, c, whereby to attach it to tbelag,and two fingers a a, one projecting transversely one way, and the otherin the opposite direction, each farenough to lap over upon the ndjacentlag, substantially as shown.' It is apparent that as these projectinglingers lie `close upon the snrfzice ofthe lags, it keeps them-inone-plane, exceptwhere theplati'orm bends inward, to

substantially as sho\vx`1 though their fornoV may very therefrom atpleasure, provided they accomplish the eiieet intended, es set forth. f

The slime rivet e which attaches abr-ace to the lng, may passalsothrough ,the connectngband, thusuniting all parts together. Where thereis e. splice in the band, 's atf, there may be two 'eyes in tliebrace,to receive two rivets, 'as shown, and any number orallof the braces mayheve double eyes if preferred. s The breces'maynbe cheaply made'of castiron. A They are applicable to horse and other animal-powers, as well-asfor the specified 'useV set forth, in. whichxthe power of dogs or othersmell animals is employed for churnv ing and-.other light work." I v 7'-Wh'at I claim ns my invention, and desire to "'sec'ure'by LettersPatent, is'

specified. The above specification signed bymo, this thirteen-th.' deyof May, 1868.
